OpenNetHome is a home automation software project with a focus on being able to mix different technologies. It currently supports a number of different RF transceivers for controlling remote switches and receiving temperature and moisture data. It also supports Philips Hue lights. Its user interface is Web based, but all features are also accessible via a TCP/IP interface. It supports plugins for new features but also for new protocol encoders/decoders. Also included is a signal analyzer tool for reverse engineering new RF protocols.
Freedomotic is an open, flexible, scalable, mashup-oriented software system which can interact with well-known standard building automation protocols and with "do-it-yourself" solutions. It treats the Web, social networks, and frontends just like any other sensor or actuator in your automation system. For example, you can tweet your washing machine to start the washing cycle. Freedomotic leverages modern enterprise integration patterns and distributed computing architectures, along with cross-language APIs for extensions.
gnhast is a collection of daemons that work together to build an event-based home automation system. Any event (such as a light being turned on) can be handled by an external script or program. These programs can be written in any language, and the central daemon handles all the intercommunication. It is designed to be easily extensible for new device types and protocols.
mochad is a TCP gateway daemon for the X10 CM15A RF (radio frequency) and PL (power line) controller, the CM15Pro RF and PL controller, and the CM19A RF controller. The CM15Pro is the EU version of the CM15A. PL support includes extended dim and status query. Standard RF modules such as motion sensors and remote controls are supported. DS10A and MS10A RF security modules are supported. Ninja pan/tilt camera mounts can be controlled from mochad. The command line interface is well-suited for CGI scripts and cron jobs. mochad works well on embedded Linux systems such as OpenWRT and Chumby, so a PC is not required for always-on applications.
nad_daemon is a daemon used to remote control NAD amplifiers over RS232. It will accept commands from the network and send them to the amplifier. It also includes a simple client. It has only been tested on the C355bee, but it should work with other amplifiers. Certain receivers from NAD will also be remote controllable in this fashion, but the more fancy features are not yet implemented.
MoCo is a system that monitors and controls SCADA points, such as temperature, HVAC, power, lighting, sprinkler systems, and more. It has industrial capabilities, but is scalable from very small home systems to enterprise, world-wide ones. It works with inexpensive I/O bridges (including X10, Insteon, and 1-wire) from a number of manufacturers. It has sophisticated history logging and diverse control capabilities, as well as a 117-page implementation manual.
